Took mine apart yesterday. Found a white plug and nothing around to plug into it. Looked at the backside of PRNDM and there was nothing that looked like a light on the inside.
Looked at any fiche available online and found nothing.
Went to Ford today. They say there should be something there. A $20 pigtail with a lamp attached.
Part is ordered and Ford dealer says they will put in in no charge.
It seems very likely that there is not supposed to be anything there. It appears this might be a factory change from many months back, an intentional change. It is really unlikely that as many as have been made sans lights, for as long as it has gone on, would not be an accident.
Essentially every new Raptor I have looked at on lots since sometime in April has not had these lights. So far I have personally looked at over 20 that do not have the lights. Seems like a long time for an error.
It makes sense that the plug would still be there, the harness probably applies to many different trim levels, some of which may have the lights.
But hay, if you can get the dealer to add them, more power to you. One person who tried to add them found there were no clips present to mount the lights, and they had to be hot glued in. That is not how the factory would do it.
T!
